Overview
The Würth Elektronik 7447709100 is a high-performance shielded drum core inductor designed for demanding power applications. Its primary function is to store energy in a magnetic field, providing crucial filtering and energy buffering in switching power supplies. A critical design consideration is the trade-off between inductance value and core saturation current; while the 10 µH inductance is ideal for many buck/boost converters, engineers must carefully manage peak currents to avoid exceeding the 10.5A saturation point, which would drastically reduce impedance and compromise circuit performance. This wirewound component leverages a manganese zinc ferrite core for optimal efficiency.
Key Features
- Inductance: 10 µH (±20%)
- Rated Current: 7.1 A
- Saturation Current (Isat): 10.5 A
- DC Resistance (DCR): 21 mOhm Max
- Shielding: Shielded
- Dimensions: 12.00mm x 12.00mm x 10.00mm (L x W x H)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- High-current filtering in DC-DC converters (e.g., buck/boost stages)
- Energy storage for pulsed power delivery systems
- Input/output ripple current reduction in automotive power modules
- EMI suppression in high-power switching circuits
